Address learning: L2 switches & bridges remembers the source hardware address of each frame received on an interface & they enter this information into MAC address table.
Forward/filter decision: When frame is received on an interface, the switch looks at destination hardware address & find exit interface in the MAC table. The frame is only forwarded out the specified destination port.
Loop avoidance: If multiple connections between switches are created for redundancy, network loop can occur, then STP is used.
